Very large percentage shown for 'Absorbing Heat' readout
I happened to notice this while printing a test piece in PP. Notice the very large percentage number for 'Absorbing Heat' readout?

Yep had that too. First 3% then 5% then this huge number starting with 4 like yours that kept changing a bit while keeping the amount of numbers, then back to 3% then 6% then back to 5% and then it was done 🙂

That could only occur within a few seconds after the Big Bang. On a more serious note, what version of the the firmware do you have installed?
RE: Very large percentage shown for 'Absorbing Heat' readout
I checked my calendar, and the Big Bang was last year sometime, so I don't think that was the cause ;).
I have the latest firmware. However, I believe the most salient fact is that I was printing with PP for the first time, with the heated bed temp set to zero. I suspect that the obviously invalid percentage was caused by dividing the current bed temp by the target bed temp - i.e. dividing by zero, giving an indeterminate value.
On a related note, this is the first time I saw the 'Skip' option displayed (although I think it is there all the time), allowing me to skip the 'absorbing heat' step. I now suspect that 'Skip' function was put in because (at least in part) because of this failure condition.

It could be a divide by zero or one that the result is cast to a different type for display. The value pictured is FFFF FFFF in hex so a 32bit number thats all 1's in binary

Firmware version?

That’s also -1 in 2’s complement.

Makes sense. Probably worth creating an incident in the GitHub repo. Definitely a bug
